The Landreth's catalog from 1882 described the Carolina Butter Bean variety as one that "offers greater probability of satisfactory return for labor expended than the most-tender lima." In other words, you get a lot of savory lima beans without putting forth much effort. They were also a favorite of Thomas Jefferson's, who grew them in his expansive garden at Monticello. Carolina Butter Bean lima pole beans, also known as Sieva, will produce quite a generous crop again and again, bearing countless green pods about 3 inches in length with several creamy white, delicately flavored beans inside. You can also stagger sowings every two weeks throughout the season for successive crops. Pole beans grow as vines that can reach 10 feet in height or more, so establishing a trellis or other structure for support is essential. This takes a bit more work in the beginning than planting bush bean varieties, but pole beans are often preferred because they tend to have better flavor, they take up less space, and the upright style of harvesting is definitely easier.
